Minimally-Invasive Technique to Replace Failed Biological Aortic Valves Successful in High Risk Patients
American Association for Thoracic Surgery (AATS)When a biologic aortic valve prosthesis fails, the patient often faces a high risk valve replacement through repeat open heart surgery. A new technique, known as Valve-in-Valve, uses minimally invasive techniques to introduce a collapsible aortic heart valve into the damaged valve in order to restore function. This procedure avoids the need to open the chest or use cardiopulmonary bypass (heart-lung machine), according to Leo Ihlberg, MD, PhD, a cardiothoracic surgeon at the Heart and Lung Center of Helsinki University Hospital, Finland, who will be presenting the results of a new study at the 93rd AATS Annual Meeting in Minneapolis on May 6, 2013.
